Careers / Expert AI evaluators

Good judgment.
Better AI.

Join Rubrex as an expert evaluator. Bring the knowledge to spot what an AI system gets wrong, explain why it matters, and help define what good looks like.

Explain the failure.
Help set the standard.

Rubrex is an AI evaluation and engineering firm. Expert evaluation connects model behavior to the requirements of real tasks.

Review with evidence

Assess AI answers, generated data, code, or agent actions against clear criteria. Identify factual mistakes, missing context, unsupported claims, and meaningful failures.

Make quality measurable

Help develop representative cases and scoring rubrics. Explain the difference between a pass, a partial result, and a failure using examples others can inspect.

Calibrate and investigate

Compare judgments, discuss ambiguous cases, and refine the criteria. Document disagreement and uncertainty instead of hiding them inside a score.

Depth in your field.
Clarity in your reasoning.

Tell us where your experience is strongest. These are areas of interest, not a list of confirmed vacancies.

Software and technical systems

Code quality, debugging, data workflows, tool use, and the behavior of software agents.

Research and subject expertise

A specialist field where you can assess correctness, source quality, assumptions, and the limits of an answer.

Language and communication

Writing quality, instruction following, multilingual behavior, clarity, and suitability for the intended reader.

Security and data practices

Relevant experience with application permissions, AI security, data handling, or privacy evidence. Assignments depend on demonstrated expertise and scope.

A score needs
a reason behind it.

Show relevant experience, careful reading, and the ability to explain a decision using evidence. Strong evaluators follow a rubric consistently, identify when it is ambiguous, and revise a judgment when the evidence changes.

We value clear written reasoning, dependable communication, and respect for confidential information. Share only work you are authorized to show.
